MUFFLER ATTACHMENT FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Applieation filed November 4, 1919. Serial No. 335,785.

.muflier of a popular type of motor-vehicle,

which is of simple, inexpensive and eflicient structure and which may be secured to the muflier by means of mufiler fastening parts so that bolts, clamps, screws or like mediumsare notv required to accompany such attachment when sold.

The invention consists of the improve ments hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from tlie following description taken in connection withthe accompanying drawings forming part hereof, and in which Figure 1, is a perspective view of the attachment embodying features'pf the invention.

21s afra vation, of a mu tachment, and c Fig. 3, is a view in cross-section, takenupon the line 33 of Fig. 2.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by .me, since the same has been found in practice to give satisfactory entary view, in side eleer equipped with the atand reliable results, although it 5 is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and de-.

scribed.

The muflier of apopular make of motor- I vehicle, as now constructed, is rovided at H its rear with a removable cap rom which projects rearwardly a short section of tubing of substantially elliptical cross-section forming a vent for the exhaust gases from the" vehicle motor. The said cap is. maintained in place by meansof a nut having screw-threaded relation with a rod extended "verted scoop-like formation, provided at its inner end with an extension 11. The forwardly extending body is disposed at an inclination with respect to said extension. The extension is provided, laterally considered, with a pair of resilient, muffler-vent engaging members 12. These members are downwardly and inwardly bent as clearly illustrated inFig. 3. The extension 11 is provided with a neck 13 which terminates in an attachment plate 14 apertured as at 15. The plate 14 is disposed substantially at right angles to extension 11.

To attach the device of the invention to a muffler the nut 16 and washer 16' of the I mufi'ler are removed, the members 12 caused to engage over the muflier vent 1 7 and the aperture 15 of plate 14 passed over the is secured against end-wise movement by nut 16 and prevented from movement around the muffler by the members 12 which engage the mufier vent.

The above described attachment serves to deflect the engine exhaust, passing through the muflier, All a direction toward the ground. It is customary to carry at the rear'of a motor-vehicle a spare tire a portion of which is in line with the muflied vent. By the employment of the attachment above described the scoop-like body thereof affords efficient protection against heat, oily soot and the like impinging against such spare tire the advantage of which is readily apparent;

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiment tible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

What I claim is: 1. In combination a muflier for motorvehicls, a cap provided with a rearwardly -projected vent of substantially e1- .liptical cross-section detachably secured to said mufller, a device having apart shaped for cooperatively engaging over said vent and for abutting agalnst said cap and hav- I said cap and device for securing same with respect to said muflier, said means being the sole method of attachment.

2. A device of the character. stated comprising a scoop-shaped body having an extension disposed at an angle thereto said extension being provided with resilient, mufiier-vent engaging members and a plate projected from said extension at substantially right-angles thereto said plate being apertured for passage over a mufiler rod to provide a means of attachment.

In witness whereof, I have hereunto signed my name.

WILLIAM F. HUDSON.
